Range Bar

This demo illustrates the range bar series type.

You can use range bars to display value ranges that correspond to specified arguments. Each point in a range bar series has one argument and two values. The argumentField supplies arguments while the rangeValue1Field and rangeValue2Field supply bar start and end point values.

To create multiple range bar series, use the series array to declare each series and the commonSeriesSettings object to specify the common series type. In this object, you can implement parameters specific to the range bar series type. For example, this demo specifies a minimum bar size for all series.
